Quantum-like classical light

Abstract: Entanglement is a quintessential property of quantum systems, and captures the fact that the state may be written in a manner that is non-separable, so that a measurement on one part affects the outcome of the other. But non-separability is not unique to quantum mechanics: weather maps are non-separable, and more pertinently, so are certain forms of structured classical light, controversially referred to as “classically entangled”. In this talk, I will outline the basics of structured light, with particular emphasis on non-separable vector states of light, and how to describe, create and detect them. Pertinently, I will show how they can be used to blur the classical-quantum divide, demonstrating quantum tools applied to the classical world, and classical beams used in quantum processes.
